M1 EVO Smart Mountain Bike Helmet | 28
12. MAINTENANCE AND CARE
The inner lining of the helmet is completely removable. Its headliner
can be washed by hand using only water, mild soap, at a maximum
temperature of 30ºC (86ºF), and non-abrasive cloths to clean the
helmet’s shell, pads and retention system. Allow the padding to dry
at room temperature. Store the helmet in a dry, dark, well-ventilated
location, out of the reach of children and animals. High temperatures
(above 110ºF, 43ºC) may melt the helmet’s shell.
WARNING
• Never use gasoline, diesel fuel, thinners or solvents to clean the
helmet. These substances can cause serious damage to the helmet,
even though the resulting damage may not be visible. This helmet
can be damaged by contact with common substances (for example,
certain solvents (ammonia), cleaners (bleach), paints, abrasives)
and this damage may not be visible to the wearer. Do not use this
helmet if it has been exposed to such substances. The full safety
function of the helmet can no longer be guaranteed if exposed to
damaging substances.
• Do not store your helmet in your car or anywhere else near a heat
source. Do not use if the shell has been melted or deformed.
Always position the helmet so that it cannot fall to the floor.
Damage that occurs in this way is not covered by the warranty.
• Do not attach anything to your helmet, including mirrors or lights.
The shell of this helmet is constructed of expanded polystyrene foam.
Ventilation holes may allow harmful objects to pass in the helmet
interior.
The protective capability of your helmet will diminish over time,
dependent upon many factors such as dents, dings, and exposure to
pollution, harmful chemicals and long term exposure to the sun. Sena
recommends that helmets be replaced after five years.
Note: The useful life of your helmet may be less than five years as a
result of exposure to sunlight, rough, handling/storage that results in
dents or cuts or as a result of heavy use.
